Ortgies & Company made only pistols chambered for 7.65mm Browning (.32 ACP), though it is clear that Heinrich Ortgies, from the beginning, also intended to produce pistols in 9mm Browning Short (.380 ACP) and 6.35mm (.25 ACP).
falsetto - a male singing voice with artificially high tones in an upper register. 1  head register, head tone, head voice - the higher ranges of the voice in speaking or singing; the vibrations of sung notes are felt in the head. 2  high-pitched, high - used of sounds and voices; high in pitch or frequency.
It's usually less for an untrained singer, possibly more for a trained singer. Falsetto can add another fifth or more to a male voice -- a generous estimate would have it adding no more than an octave. Among men, the broad categories are bass (about E2-F4), baritone (about G2-Ab4), and tenor (about Bb2-C5).
